any kind of link, be it smb:// nfs:// etc. when in fact it only makes sense for
http/https links. Opening links that the user has clicked on is not very
problematic but can be used to chain to other attack vectors. Given the
intended functionality of the feature is just for http/https links it makes
sense to do that verification (CVE-2021-28117).");
